The United States has recorded between 2,295 and 2,318 measles cases in 2026, the highest annual total since 1991. Health experts and the CDC attribute the surge to declining MMR vaccination rates among kindergarteners, which have fallen below the 95% herd immunity threshold. Outbreaks are linked to unvaccinated residents contracting the virus during international travel, with children and teenagers accounting for 69% of infections.
